Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Dissertations and Theses
In dynamic environments, split-second sensorimotor decisions must be prioritized according to potential payoffs to maximize overall rewards. The impact of relative value on deliberative perceptual judgments has been examined extensively, but relatively little is known about value-biasing mechanisms in the common situation where physical evidence is strong but the time to act is severely limited. This research examines the behavioral and electrophysiological indices of how value biases split-second perceptual decisions and the possible mechanisms underlying the process. In prominent decision models, a noisy but statistically stationary representation of sensory evidence is integrated over time to an action-triggering bound, and value-biases …
Effect Of Menstrual Cycle On Hedonic Response To Gustatory Stimuli, Laurie Ann O'Toole
Effect Of Menstrual Cycle On Hedonic Response To Gustatory Stimuli, Laurie Ann O'Toole
Dissertations and Theses
The present experiment was conducted to determine the relationship between the human menstrual cycle and gustatory hedonic response. Hedonic response was defined as the perceived pleasantness or unpleasantness of a taste stimulus. Gender differences in taste hedonic have been observed; these may be due to differences in endocrine systems. Animal taste preferences are altered when reproductive hormonal status is experimentally manipulated. Previous researchers report that human females' hedonic responses to sucrose vary systematically with phase of menstrual cycle.
